Introduction to the classification and characteristics of polymer lithium batteries

Solid polymer electrolyte lithium ion battery electrolyte is a mixture of polymer and salt. This battery has low ionic conductivity at room temperature and can be used at room temperature. Gel-gel polymer electrolyte lithium-ion batteries add plasticizers and other additives to the solid polymer electrolyte, and then improve the ion conductivity, so that the battery can be used at room temperature. Lithium-ion batteries with polymer polymer cathode materials use conductive polymers as cathode materials, and their specific capacity is relatively increased. Because solid electrolytes are used instead of liquid electrolytes. Compared with liquid lithium-ion batteries, polymer lithium-ion batteries have the advantages of being thinner, arbitrarily large, and arbitrarily shaped. Therefore, aluminum-plastic composite films can be used to make battery casings. Improve the specific capacity of the entire battery; polymer lithium-ion batteries can also use polymer as the positive electrode material, and its mass specific energy will be more than 20% higher than that of current liquid lithium-ion batteries. The polymer lithium ion (PolymerLithium-IonBattery) battery has the characteristics of miniaturization, thinning, and light weight. Therefore, the market share of polymer batteries will gradually increase. 2Characteristic polymer lithium ion battery has the following characteristics[2]: ① shaping flexibility; ② higher mass specific energy (3 times that of MH-Ni battery); ③ wide electrochemical stability window, up to 5V; ④ perfect Safety and reliability; ⑤Longer cycle life, less capacity loss; ⑥High volume utilization; ⑦Wide application areas.
